iOS10--消息通知的基本使用

r囧r小猫 2022-06-15 23:59 287阅读 0赞

官方将通知单独放在了UserNotifications.framework，使用时需要导入框架。  
UserNotifications.framework主要类文件：

> UNCalendarNotificationTrigger  
> UNLocationNotificationTrigger  
> UNMutableNotificationContent  
> UNNotification  
> UNNotificationAction  
> UNNotificationAttachment  
> UNNotificationCategory  
> UNNotificationContent  
> UNNotificationRequest  
> UNNotificationResponse  
> UNNotificationServiceExtension  
> UNNotificationSettings  
> UNNotificationSound  
> UNNotificationTrigger  
> UNPushNotificationTrigger  
> UNTextInputNotificationAction  
> UNTextInputNotificationResponse  
> UNTimeIntervalNotificationTrigger  
> UNUserNotificationCenter

#### UNUserNotificationCenter的应用： ####

*  **请求用户授权：**
    
        UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];    
        // 请求授权    
        /*     
        UNAuthorizationOptionBadge   = (1 << 0),     
        UNAuthorizationOptionSound   = (1 << 1),     
        UNAuthorizationOptionAlert   = (1 << 2),     
        UNAuthorizationOptionCarPlay = (1 << 3),     
        */    
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound + UNAuthorizationOptionBadge)                          completionHandler:^(BOOL granted, NSError * _Nullable error) {                             
        }];
    
    `补充：`获取授权设置信息
    
        // 获取通知授权和设置    
        [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {        
        /*         
        UNAuthorizationStatusNotDetermined : 没有做出选择         
        UNAuthorizationStatusDenied : 用户未授权         
        UNAuthorizationStatusAuthorized ：用户已授权         
        */        
        if (settings.authorizationStatus == UNAuthorizationStatusNotDetermined) 
        {                       
              NSLog(@"未选择");                  
        }else if (settings.authorizationStatus == UNAuthorizationStatusDenied){                        
              NSLog(@"未授权");                   
        }else if (settings.authorizationStatus == UNAuthorizationStatusAuthorized){                      
              NSLog(@"已授权");        
        }       
        }];
 *  **创建本地通知：**
    
        // 创建一个本地通知
        UNMutableNotificationContent *content_1 = [[UNMutableNotificationContent alloc] init];    
        // 主标题    
        content_1.title = [NSString localizedUserNotificationStringForKey:@"title" arguments:nil];    
        // 副标题    
        content_1.subtitle = [NSString localizedUserNotificationStringForKey:@"subtitle" arguments:nil];    
        content_1.badge = [NSNumber numberWithInteger:1];    
        content_1.body = [NSString localizedUserNotificationStringForKey:@"title_message_for_yan" arguments:nil];    
        content_1.sound = [UNNotificationSound defaultSound];    
        // 设置触发时间    
        UNTimeIntervalNotificationTrigger *trigger_1 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:10 repeats:NO];    
        // 创建一个发送请求
        UNNotificationRequest *request_1 = [UNNotificationRequest requestWithIdentifier:@"my_notification" content:content_1 trigger:trigger_1];
    
    `补充：`
    
     *  UserNotifications提供了三种触发器：
        
            UNTimeIntervalNotificationTrigger ：一定时间后触发
            UNCalendarNotificationTrigger ： 在某月某日某时触发
            UNLocationNotificationTrigger ： 在用户进入或是离开某个区域时触发
     *  @“my\_notification”请求的标识符可以用来管理通知：
        
            - 移除还未展示的通知
            [center removePendingNotificationRequestsWithIdentifiers: @[@“my_notification”
            ]];
            [center removeAllPendingNotificationRequests]; //  - (void)cancelAllLocalNotifications；
            - 移除已经展示过的通知
            [center removeDeliveredNotificationsWithIdentifiers:@[@“my_notification”
            ]];
            [center removeAllDeliveredNotifications];
            - 获取未展示的通知    
            [center getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest *> * _Nonnull requests) {
               NSLog(@"%@",requests);    
            }];    
            - 获取展示过的通知    
            [center getDeliveredNotificationsWithCompletionHandler:^(NSArray<UNNotification *> * _Nonnull notifications) { 
              NSLog(@"%@",notifications);
            }];
     *  远程通知的格式：
        
            { "aps":{ "alert":{ "title":"I am title", "subtitle":"I am subtitle", "body":"I am body" }, "sound":"default", "badge":1 } }
        
        具体请参考[官方文档][Link 1]
 *  **将通知请求添加到通知中心（UNUserNotificationCenter）：**
    
        [center addNotificationRequest:request_1 withCompletionHandler:^(NSError * _Nullable error) {       
          }];

接收通知

*  **处理通知：**  
    设置UNUserNotificationCenterDelegate：  
    `注意：`UNUserNotificationCenter 的 delegate 必须在 application:willFinishLaunchingWithOptions: or application:didFinishLaunchingWithOptions:方法中实现；
    
        center.delegate = self;
    
     *  应用内展示通知:
        
            - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
            // 如果不想显示某个通知，可以直接用空 options 调用 completionHandler: // completionHandler([])
            
            completionHandler(UNNotificationPresentationOptionBadge + UNNotificationPresentationOptionSound);   
            }
     *  在用户与你推送的通知进行交互时被调用：
        
            - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{    
            completionHandler();       
            NSLog(@"userInfo--%@",response.notification.request.content.userInfo);
            }

#### **UNNotificationCategory的应用：** ####

*  **创建一个 category：**
    
        /*     
        UNNotificationActionOptionAuthenticationRequired = (1 << 0),    
        UNNotificationActionOptionDestructive = (1 << 1), 取消     
        UNNotificationActionOptionForeground = (1 << 2), 启动程序     
        */   
        UNTextInputNotificationAction *textAction = [UNTextInputNotificationAction actionWithIdentifier:@"my_text" title:@"text_action" options:UNNotificationActionOptionForeground textInputButtonTitle:@"输入" textInputPlaceholder:@"默认文字"];    
        UNNotificationAction *action = [UNNotificationAction actionWithIdentifier:@"my_action" title:@"action" options:UNNotificationActionOptionDestructive];    
        UNNotificationAction *action_1 = [UNNotificationAction actionWithIdentifier:@"my_action_1" title:@"action_1" options:UNNotificationActionOptionAuthenticationRequired];    
        /*     
        UNNotificationCategoryOptionNone = (0),     
        UNNotificationCategoryOptionCustomDismissAction = (1 << 0),     
        UNNotificationCategoryOptionAllowInCarPlay = (2 << 0),     
        */    
        UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"my_category" actions:@[textAction,action,action_1] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];    
        NSSet *setting = [NSSet setWithObjects:category, nil];    
        [center setNotificationCategories:setting];
 *  **在创建 UNNotificationContent 时把 categoryIdentifier 设置为需要的 category id 即可：**
    
        content.categoryIdentifier = @"my_category";
    
    > 远程推送也可以使用 category，只需要在 payload 中添加 category 字段，并指定预先定义的 category id 就可以了
 *  **处理category的通知：**
    
        - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{    
          completionHandler();       
          NSLog(@"userInfo--%@",response.notification.request.content.userInfo);       
        // 获取通知中心的所有的Categories    
        [center getNotificationCategoriesWithCompletionHandler:^(NSSet<UNNotificationCategory *> * _Nonnull categories) { 
                    for (UNNotificationCategory *category in categories) { 
                 if ([category.identifier isEqualToString:@"my_category"] && [response.notification.request.content.categoryIdentifier isEqualToString:@"my_category"]) { 
                        for (UNNotificationAction *textAction in category.actions) {
                                 if ([textAction.identifier isEqualToString:@"my_text"]) { 
                                               UNTextInputNotificationAction *text = (UNTextInputNotificationAction *)textAction;
                                               UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:text.textInputButtonTitle preferredStyle:UIAlertControllerStyleAlert];
                                              [alert addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleCancel handler:nil]]; 
                                              [[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:alert animated:YES completion:nil];
                                  }
                      } 
                 }
              }
        }];
        }
